They don’t have Mozartists.

This approach sounds good.

I think the correct approach is both, if you have the option.

Most devices accept two name servers. Redundancy is always good, especially for DNS.

I’ve used this list generating package for years now with great results: https://github.com/opencoff/unbound-adblock/tree/master

It is designed to generate blocking lists that can be used with unbound, the DNS resolver. There are even instructions for how to configure unbound so if you are new to it all you can follow along.

I use the resulting lists in my two local DNS name servers, running unbound.

The way it works is that if a query for a blocked address comes in to one of thenlocal DNS servers it returns a domain not found result. If the address is not on the block list then it forwards the query on to an internet DNS resolver securely using DoT.

You can gain further control over your DNS results by choosing those upstream resolvers carefully. Quad9 and Cloudflare etc all offer DoT resolving, along with some further filtering (eg. for malware), or completely unfiltered DNS if that’s what you want.

Services like cleanbrowsing.org offer more fine grained filtering, useful if you want a family-friendly set of DNS results, based off categorify.org. You can pay for really fine tuned results, or there is a free layer which provides still very useful basic categories.

Combining the two forms of filtering, local advert and tracking blocking, along with open internet content categorisation, seems to be very effective.

I get complaints about too many adverts when my kids are on WiFi away from home. I take it as a compliment.

Edit: Forgot to mention! Another minor gripe I have is that my current 1 router / 2 routers-as-AP solution isn’t meshed, so my devices have to be aware of all 3 networks as I walk across my property. It’s a pain that I know can be solved with buying dedicated access points (…right?), but I’d like to know other’s experiences with this, either with OpenWRT, or other network solutions!

This works very well with OpenWRT on each AP and/or router device by using the same ESSID and password combo on each of them, enabling WLAN roaming and also 802.11r Fast Transition to allow your mobile devices to hand-off quickly from one AP to another as signal strength levels demand. With this enabled you keep the same IP address, and even SSH sessions don’t drop when you move from one AP to another, it all happens in the background. As far as the end-user is concerned it is all just one big happy wifi network.

802.11r is not mesh, that’s a separate thing but and you can do it with OpenWRT too. I don’t need to because I have ethernet to all my APs, so all the RF bandwidth is available for the last leg from AP to device(s), and not being used by back-haul from AP to AP through to the router as well.

In your use case I would consider grouping devices into categories and having a different wifi network for each category with the dhcp and firewall rules set accordingly.

VLANs on the ethernet-side might also be useful, but it sounds like most of your devices are on WiFi, so it might well be possible to get a “mature” setup without needing that extra complexity.

As others have said, backing these settings up and restoring them to a new device in the case of hardware failure is generally straightforward. Care is needed when replacing the broken device with a new one because of naming conventions varying from device to device, but the network logic, and things like dhcp reservations can be carried over.

Check that it works with Klipper!

The convenience and control Klipper provides is phenomenal. You don’t have to use it if it turns out you dont like it, but I feel like ruling it out as an option now would be a shame.

I would also point out that you should not be put off by the “official” supported printers list for Klipper, a bit of Googling will often turn up some mini projects where people are actively working on supporting the printer with Klipper before the main project gets round to adding official support.

Thank so much for this survey. So much useful detail. Great stuff!

You mention Blender in passing. Any thoughts on using it for CAD design for 3d printing? “Keep Making” on YouTube seems to love it for that, once some plugins are installed.

I think such a dataset would be very useful. I’m just getting in to 3D printing and have spent a little bit of time hunting for this type of information already. I’ve had to stick to star ratings on vendor sites so far.

• What are the physical properties it would be useful to track?
• How are they measured/which standard is being followed?
• How do they relate to practical matters like ideal extruder temperature and velocities for particular properties or effects?
